Firewatch Day 77 Bug?

I just started Firewatch last night after buying it first thing last week on Ps4. It's been one of my most anticipated games, but I've hit a spot where the game can't progress.

Spoilers

On Day 77, when Delilah tells you to go to Cottonwood Creek, I went to what I thought was Cottonwood Creek, but did not find anything to interact with, so I instead decided to head over and break through the fence. I have the wave length device, and now the game is telling me to go back to the lookout tower. But when I go back to the tower, nothing happens. No prompts, no nothing. I eventually figured out where the actual Cottonwood Creek is, and Delilah told me to open the cache box (which a new radio is supposed to be in there I've read). But the box is empty, with only a book in there. I have headed back to the tower to see if that would trigger something but still nothing. I really do not want to restart the game from the beginning.

I'm not sure what to do to correct this problem, so I figured I would post here to see if anyone had any similar issue. I have loved this game so far, but it's strange to be how this got through Playstation's certification. The game shutters, drops in frames per second, freezes on the load screen, and there are game breaking bugs. Hopefully these things get ironed out in a patch.

I had a similar problem on my first playthrough (PC). Went to Cottonwood Creek and walked around the entire area for a good while and Delilah never radioed me and there was no radio in the box. Luckily I had copied a previous save earlier in the game. I loaded that save and when I got to the Cottonwood Creek she radioed me this time and there was a radio in the box. I'm curious though, were you talking with Delilah normally while getting the wavelength device? I guess you could try closing out of the game and then starting it back up.

Yep. I went to Wapiti Station first, figured for some reason I had to go back to the tower (no dialogue from D about the tree poster at the beginning of the day, and she was chastising me for not figuring out the clues, which I hadn't heard from her), then made my way to the meadow to find the new radio. Opened with the new code, and there was no radio. Lots of vague rustling, no radio. And no old save. So after having sunk hours in, wondering if I have to restart. This is dismaying to say the least. Did you find a workaround?
